I also test the same operations on R 3.6.3. The CPU usage does not change dramatically. C:\Users\Jinso>typeperf "\Process(Rgui)\% Processor Time" -si 5 ... "04/28/2020 13:42:41.007","-1" "04/28/2020 13:42:46.017","-1" "04/28/2020 13:42:51.037","0.622240" "04/28/2020 13:42:56.048","0.00" "04/

I give up. (I was trying to emulate the top command). You might have to manually type the contents of the task manager, with process name and CPU usage. That's if you still want to fix the problem... On Tue, Apr 28, 2020 at 8:44 AM Abby Spurdle wrote: > > Just realized CPU(s) is time the process

What's the benchmark? I (still) have Windows 10 x64. Opening the task manager, causes the CPU to jump to over 90%. In regards to the CPU usage remaining high: (1) Are you running R in a standard way? (2) If (1) true, is R idle (i.e. waiting for user input)? (3) If (2) true, how much CPU is R usin
